The invention discloses a device for improving the dirt measuring work efficiency of an electric transmission line porcelain insulator. The device comprises a container, the upper edge of the container is connected with a first support and a second support, the side, towards the center of the container, of the middle of the first support is connected with one end of a connecting rod, the other end of the connecting rod is connected with a fixed clamp, a first spraying head is arranged at the position, below the fixed clamp, of the first support, the side, towards the center of the container, of the middle of the second support is provided with a second spraying head, the side wall inside the container is connected with one end of a first annular frame, the other end of the first annular frame is connected with a first ring, and first filter paper is placed on the first ring. According to the device, the insulator can be vertically fixed to the device for improving the dirt measuring work efficiency of the electric transmission line porcelain insulator, cleaning sewage is prevented from being splashed out of the device for improving the dirt measuring work efficiency of the electric transmission line porcelain insulator in the cleaning process, and therefore the accuracy of dirt measurement is greatly improved.
